MINING AND QUARRYING MACHINE.

Application filed June 24, 1919, Serial No. 306,335. Renewed October 28, 1922. Serial No. 597,t83.

To all whom it may concern:

Be it known that I CYRUS S. OLDROYD, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Mining and Quarrying Machines, of which the following is a specification, reference being'had to the accompapiying drawing.

1 y improvement relates particularly to machines used for cutting into upright. walls of coal, rock, or similar material, .the machine comprising cutting means actuated by the machine and projected endwise into the wall of coal, or other material, and then moved sidewise to make a sweeping cut; the cutting mechanism being, however, adapted to cut in a variety of other ways.

By way of general statement, it may be said that the machine to which this invention relates consists of (1) a truck having a rigid frame or body and having supporting or traction wheels adapted to rest on ordinary rail tracks or on a floor; (2-) a neck located at the front of the truck body and rotatable on a horizontal axis extending lengthwise of the machine and approximately in an upright plane cutting midway between the track rails; (3) and cutting mechanism supported by said, neck and adapted to be adjusted for cutting in various directions.

The object of the present improvement is to provide an eflicient means for at the will of the operator transmitting motion from a motor located on the body of the machine to the above-mentioned neck for turning the latter on its horizontal axis for the purpose of imparting to the cutting mechanism supporting means a portion of the movements to which said supporting mechanism is subjected for the change of direction of cutting.

For such cutting mechanism as has been above indicated, reference is here made to my application for Letters Patent of the United States Serial Number166,l72,.. filed May 3, 1917, for an improvement in mining and quarrying machines.

In the accompanying drawings,

Fig. 1 is an elevation of the right hand side of a machine embodying my improvement, the cutting mechanism. being shown the same as in my said application Serial Number 166,172;

I of

Fig. 2 is a plan of the same machine, a

part of the cutting mechanism being omitted 6-6,. of Figs. 1 and 3, looking toward the right;

Fig; 7 is an upright section on the line, 7-7, of Fig. 3;

the neck of the cutting mechanism supporting means.

Referring to said drawings, A are four track wheels resting on track rails, R. Said wheels are arranged in pairs on two horizontal axles, A. Each of said axles rests in bearings, A, formed on the lower part of the body, A, of the machin Saidbody has a floor or bed, A, and 'a right hand upright wall, A and a left hand. upright wall, A and a rear cross wall, A, and afront cross wall, A.

Immediately at the rear of the rear cross wall, A, is an electric motor, M, having a shaft, M from which power is to be transmitted to the neck, D.

In the fr0nt.cross wall, A", on the axialline of the motor, is a hearing, A", in which rests the neck, D, which supports the cutting mechanism, E. Said bearing is formed by cutting out the upper edge of the cross wall, A, and the lower edge of a bearing block, A", which rests upon the upper edge of the -wall, A, and between the side walls, A

and A.

The rear end of the neck projects through said bearing andis there surrounded b a worm gear wheel, D which bears agalnst the rear face of said cross wall. B this means the forward movement of sai' neck is prevented. Immediately at the rear of the worm wheel is a. friction clutch member, D, which has a sleeve, D", extending forward into the neck. A neck shaft, D, lying within. the neck extends rearward into the forward portionof said-sleeve and is keyed Fig. 8 is an upright section along the line spiral gear to the sleeve, so that said clutch member and said sleeve and said shaft must rotate in unison. At the rear of the neck shaft, the sleeve, D receives and forms a bearing for the forward end of the main transnrission shaft, B, which is joined to the motor shaft, M by means of a coupling, M

The function of the neck shaft is to transmit power to the cutting mechanism as described in my said application Serial Number, 166.172. Rotation is imparted to the worm wheel, I), and the neck, D, by the mechanism which will now he described.

On the main transmission shaft, B, is a spiral gear wheel, B, which meshes with a wheel, B which is loose on the upright shaft. 13*, which rests in bearings, B and B. On the bearing, 13, rests the lower end of a spacing sleeve. B which loosely surrounds the shaft, B", and supports a bevel gear wheel, B which is cast integral with the spiral gear wheel, B. The bevel gear wheel, B, meshes with the bevel gear wheel, B which is fixed on a shaft, B", resting in a bearing, B and extending through the side wall, A On the shaft, B, is feathered a jaw clutch, B, which is adapted to engage in the upright face of the wheel, B for the transmission of motion from said wheel, to said shaft. A bevel gear wheel, 13, is fixed on the lower end of said shaft and meshes with a bevel gear wheel, A, which is fixed on one of the axles, A Thus motion is transmitted from the main transmimion shaft, B, to said axle.

Integral with the bevel gear wheel 8 is a spur gear wheel, (3, which meshes with a spur gear wheel, C, which loosely surrounds a: shaft, C which is horizontal and transverse to the length of the machine and has one end resting in a bearing, C rising from the floor of the body of the machine and having its other end resting in a hearing, .C, formed in the right hand upright wall, A of the machine body. Said shaft extends outward through said wall and there has fixed upon it a spur gear wheel, 0*, which meshes with a larger spur gear wheel. C", which is fixed on the shaft, G which is horizontal and transverse to the length of the. machine and rests in the bearing, C and in bearings, C formed in the end walls of an oil trough, C Between the two bear ings, C the shaft, C, bears a. gear worm, C, which engages the worm wheel, D already described as being supported on the neck, D.

Constant rotation is imparted from the spiral gear wheel, B through the bevel gear wheels, B and B and the spur gear wheel, C, to the spur gear wheel, 0. But since the latter wheel is normally loose on the shaft, C said shaft does not rotate exce-pting when enga ment between said shaft and said whee is effected by means of the jaw clutch,

C", which surrounds the shaft, C and is feathered thereto to permit sliding endwise and to compel rotation with the shaft. hen said clutch is in engagement with the wheel, C the clutch and the shaft, C take motion from said wheel. A ring, C rests in an annular groove, C formed on the clutch. The fork, C, of the upright clutch lever, C engages said ring. Said lever is pivoted to an ear, C", placed on the inner face of the wall, A}. The upper end of said arm is coupled to the right hand end of a connecting bar, C, which is horizontal and transverse to the length of the machine and has its opposite end coupled to one arm of a bell crank, C, which is located in a horizontal plane and hinged at C to the rear face of the bearing block, A. To the other arm of the bell crank is coupled the forward end of a slide rod, 0, which extends rearward through a guide, C formed on the inner face of the left hand wall, A lVhen the operator shifts said rod forward the fork, C and the clutch, move away from the wheel, C and shifting the ro C rearward causes the movement of the fork, C, and theclutch toward the wheel, C

The trough, C is to contain sufficient oil to partially immerse the worm, C, whereby the worm takes oil for the lubrication of the engagement between the worm and the worm wheel, I).
